Granted: 1899-07-22
Abstract: 18,583. Belfield, R., [Lamme, B. G.]. Aug. 30. Motors, alternating-current; controlling.-An alternating-current induction motor is provided with means for securing a variable speed with a large starting torque, for obtaining a constant speed with less than the rated load, and for operating the motor at different speeds without any substantial variation in torque. The invention is particularly useful in connection with motors employed for crane and elevator work. The primary member of the motor 1 is supplied with a variable electromotive force by means of transforming 6, 8 and 7, 9, the secondaries of which are divided up as shown in the Figures and provided with switches 12 for varying the number of sections in circuit. In the form shown in Fig. 1, the switches are intended to be actuated by hand, but they may be actuated automically, as the load of the motor varies, by means of solenoids in the primary circuits of the motor. For securing constant torque with variable speed, choking-coils 19 are inserted in the primary circuits of the motor, as shown in Fig. 5.

Title: Improvements in or relating to Driving and Braking Mechanism, particularly applicable to Motor Vehicles.
Inventor: BOULT ALFRED JULIUS
Filed: 1898-12-30
Granted: 1899-11-25
Abstract: 27,525. Boult, A. J., [Darracq & Co., A.]. Dec. 30. Motor road vehicles.-Relates to driving and braking mechanism applicable to motor carriages, and also to tricycles and the like furnished with pedalling gear. Fig. 1 shows in horizontal section, and Fig. 2 in side elevation, one form of the driving-mechanism. Motion is transmitted from the driving-shaft A to the driven shaft B, which is in two parts connected by differential spur and pinion gear. by means of a spur-wheel D, with which can be made to engage either the pinion E or E' according to the speed desired. These pinions are carried on a swinging arm F, the movement of which is limited by fixed stops. The spur - wheel D is composed of a central portion D<1> and an outer toothed ring, which is kept in frictional engagement with the central part by a conical ring O<1> pressed between the two by springs. The springs and conical ring are so adjusted as to be able to transmit only the maximum power desired ; owing to slip being thus possible, shock is avoided when the gear is charged or at other times. When pedalling gear is provided, the gear includes a chain-wheel L, and the whole gear is enclosed in a suitable casing. This surrounds the chain-wheel closely and prevents the chain from coming off ; in the casing is an opening M for taking the chain off or putting it on. The chain-wheel is connected with the axle by a roller clutch, so that it is free after the motor has started. A brake drum is provided at N<11>. In a modification, Fig. 4, there is combined with the chain-wheel a second clutch that acts only in the opposite direction to the driving - clutch. By means of this the brake can be applied by backpedalling. The backward motion is communicated from the chain-wheel L to the brake, so as to put it into action through the medium of a toothed wheel M<4> and sector.
